Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of ransaxle, and this ransaxle comprises a plurality of parts such as retarder, differential mechanism.In the situations such as vehicle is turning to, differential mechanism can distributed power, and the driving wheel of both sides is rotated with different rotating speeds.
Wherein, the differential casing of differential mechanism is positioned at reducer shell 3, and differential casing comprises and being fixedly connected with that first differential casing 5 of (connecting by cross axle) and the second differential casing 6, the first differential casings 5 and the second differential casing 6 are installed in respectively on the first semiaxis 1 and the second semiaxis 2.Relatively rotate owing to existing between reducer shell 3 and the differential casing, thereby between reducer shell 3 and the first differential casing 5, clutch shaft bearing 7 is installed, and between reducer shell 3 and the second differential casing 6, the second bearing 8 is installed, to realize relatively rotating between reducer shell 3 and the differential casing.Shown in the figure, clutch shaft bearing 7 is the identical tapered roller bearing of diameter with the second bearing 8, but is not limited to tapered roller bearing.
In the utility model, with respect to clutch shaft bearing 7 and the second bearing 8, will look closely the inner for clutch shaft bearing 7 and the second bearing 8 towards one of differential mechanism, with an outer end of looking closely for clutch shaft bearing 7 and the second bearing 8 of differential mechanism dorsad.In addition, " width " in the utility model refers to along the length of the axial direction of the first semiaxis 1 and the second semiaxis 2.
As shown in the figure, be separately installed with the first adjusting nut 26 and the second adjusting nut 22 in the outer end of clutch shaft bearing 7 and the second bearing 8.Particularly, the first adjusting nut 26 and the second adjusting nut 22 are installed on the inner peripheral surface of reducer shell 3, respectively clutch shaft bearing 7 and the second bearing 8 being applied axial pretightening force, thereby prevent in the axial direction play of clutch shaft bearing 7 and the second bearing 8.The first adjusting nut 26 and the second adjusting nut 22 can be installed on the inner peripheral surface of reducer shell 3 in several ways, for example in the present embodiment, adjusting nut 22 is threaded connection on the inner peripheral surface of reducer shell 3, thereby can tighten or unscrew the first adjusting nut 26 and the second adjusting nut 22, to adjust respectively the axial pre tightening force to clutch shaft bearing 7 and the second bearing 8.
In addition, at ransaxle differential lock is installed, differential mechanism can be pinned, make it not produce differential action, so that vehicle travels under the not good situation of pavement behavior.Be appreciated that, for realizing the differential lock function, ransaxle in prior art increases differential lock, need to (for example improve the structure of reducer shell 3 and axle housing 4, reducer shell 3 need to be increased, need to improve the Chinese lute hole of axle housing 4 etc.), to adapt to the differential lock of increase.It is relatively large that but reducer shell 3 itself has structure, the characteristics such as complex structure.Generally, reducer shell 3 castings form, if baroque reducer shell 3 is carried out architecture advances, need again die sinking, and this has increased the manufacture cost of reducer shell 3 undoubtedly.
In order to save the manufacture cost of reducer shell 3, the utility model is installed in the fixed engagement cover 11 of differential lock between reducer shell 3 and the second differential casing 6, makes fixed engagement cover 11 be positioned at the outer end of the second bearing 8.And be width less than clutch shaft bearing 7 with the width design of the second bearing 8, so that the width sum of the width of the second bearing 8 and fixed engagement cover 11 is substantially equal to the width sum of width and first adjusting nut 26 of clutch shaft bearing 7.In other words, reduce by the width with the second bearing 8, to reserve the installing space of the fixed engagement cover 11 that differential lock is installed, therefore needn't improve the structure of reducer shell 3 and axle housing 4, improve the versatility of reducer shell 3 and axle housing 4, saved the development cost of reducer shell 3 and axle housing 4.
Can find out at said structure, because the width of the second bearing 8 reduces, and reducer shell 3 roughly is symmetrical structure, therefore, the width that reduces in order to compensate the second bearing 8, in a kind of embodiment, can make the first adjusting nut 26 have different width with the second adjusting nut 22, the second adjusting nut 22 that namely adopts width relatively to increase, compensate with the width that the second bearing 8 is reduced, so that the width sum of the second adjusting nut 22 and the second bearing 8 equals the width sum of the second bearing 8 and fixed engagement cover 11.In another kind of embodiment, can make the first adjusting nut 26 have identical width with the second adjusting nut 22, and between the second adjusting nut 22 and the second bearing 8, spacer 23 is set, thereby compensate the width that reduces by the second bearing 8 by spacer 23, so that the width sum of the second adjusting nut 22, spacer 23 and the second bearing 8 equals the width sum of the second bearing 8 and fixed engagement cover 11.
Need to prove, the second adjusting nut 22 and spacer 23 all are positioned at the periphery of fixed engagement cover 11, and and there is the gap between the fixed engagement cover 11, thereby when relatively rotating between differential casing and reducer shell 3, the second adjusting nut 22 and spacer 23 can not hinder 11 rotations with the second differential casing 6 of fixed engagement cover.Also need to prove, clutch shaft bearing 7 and the second bearing 8 in the utility model be in the situation that adopt tapered roller bearing, and width and the fixed engagement that should be understood to the inner ring of the second bearing 8 overlapped the width sum that 11 width sum is substantially equal to width and described first adjusting nut 22 of clutch shaft bearing 7.And if clutch shaft bearing 7 and the second bearing 8 are the situation of roller bearing, because the Internal and external cycle width of bearing is identical, thereby do not need to specify.
In addition, for ease of installation and removal, the fixed engagement of differential lock cover 11 by splined on the outer circumferential face of the second differential casing 6.And between the outer circumferential face of fixed engagement cover the 11 and second differential casing 6, back-up ring 20 is set, particularly, correspondingly be provided with circular groove (not indicating) on the inner peripheral surface of fixed engagement cover 11 and on the outer circumferential face of the second differential casing 6, described back-up ring 20 is contained in the circular groove, with moving axially of restriction fixed engagement cover 11.In above-mentioned splined structure, can improve linking intensity by taking larger spline tooth, but in the situation that increase the spline size, correspondingly may weaken the intensity of the second differential casing 6, thereby, in the present embodiment by splined section is quenched, thereby improve the intensity of spline, and then improve the intensity of splined structure.
Simultaneously, because fixed engagement cover 11 is installed on the second differential casing 6, for further improving the intensity of splined, can make Cast Steel or the forging of the second differential casing 6 strength increases.And the structure of the first differential casing 5 is not improved, in the situation that satisfy structural strength, for improving versatility and saving cost, the first differential casing 5 still adopts ironcasting.
